I had use opa604 in my machine， its good， but I hoped this can be better。 after a lot of reaching work， I get 4 v6 classics first。 its sounds smooth and soft， details still be there。 I like it very much。 Then I wanna know how the vivid should be。so I get another 4 v6 vivid s for my machine。 a little more energy， sound a little younger， faster。 and the details are more clear。 I love them both。 maybe， classic is a little more。。。
